Explanation

The boy got 25 marks and failed by 15, meaning the passing mark is 25 + 15 = 40. The percentage of pass marks is (40 / 80) * 100 = 50%.

AI explanation

The passing marks equal the marks obtained plus the failing margin, which is 25 + 15 = 40 marks. To find the percentage of pass marks, divide the passing marks by the total marks and multiply by 100, yielding (40 / 80) * 100 = 50%. The pass marks percentage is 50%.
